Could Jailbreaking Cause My WiFi to be Funky?

My WiFi was working great last night when I bought it. Then I decided to Jailbreak it using that one click jailbreak method through my touch and didn't really notice anything wierd last night. But today I am having massive issues with my WiFi, I can barely connect to anything and it's really slow. And now I can't even connect to the same WiFi spot that I was using last night just fine! The hotspot shows up on the list and then when I tap it it just says it can't connect to it! And earlier I couldn't even find hotspots! Should I try restoring it and see if it works again with stock set up?

Btw im on my laptop using this exact WiFi spot that I was using last night with my laptop and my touch just fine, now my laptop can connect perfectly but the touch cant! what gives!?
